## URL Format

**POST** https://[site].chargebee.com/api/v2/currencies/{site-currency-id}

## Input Parameters

- `forex_type` (required, enumerated string)
  This represents the exchange rate type set for the currency.
  Possible enum values:
    - `manual`
      If `forex_type` is `manual` , you will be able to set the conversion rate for the currency. You need to update the exchange rate each time your exchange rate provider changes it
    - `auto`
      If `forex_type` is `auto` , conversion rate will be auto updated by Chargebee every day with third party providers (using external currency conversion providers)

- `manual_exchange_rate` (optional, string, max chars=20)
  This parameter allows you to pass the exchange rate in decimal format. When `forex_type` is `manual` you have to set the exchange rate for additional currencies in `manual_exchange_rate` parameter. A maximum of **nine** decimal values are allowed to pass in this field.

## Returns

- `currency` (Currency object)
  Resource object representing currency
